Shinv Mountain Ruins

　　Shinv Mountain Ruins are located in Shinvshan Village, Yonglong Town, Jingshan County. The site is situated on an independent hill in a plain region, featuring an irregularly shaped, flat-topped summit covering an area of about 7,000 square meters. Except for a small hill in the eastern part, the site is mostly flat. To the southeast of the ruins lie Tianjiawan Ruins and Tianjiashan Ruins, while 600 meters to the north is Baijiangtai Ruins, and 600 meters to the west lies Chenjiadang Zhujiawan. The cultural layer at the site is approximately 1.2 meters thick. Collected artifacts include stone tools and pottery—stone tools mainly consist of stone shovels, while pottery is predominantly gray earthenware, with small amounts of black and red pottery. The decorations are mostly plain, with occasional rope patterns. Artifact types include tripods, bowls, basins, jars, as well as rope-patterned roof tiles and tubular tiles.
